TeamSpeak belongs to a group of programs offering voice communications on the Internet based on the VoIP technology. This is probably the most popular tool among the players, which they can use to communicate in real time in online team games. The program is characterized by high-quality sound, coming from the well implemented mechanism of reducing noises from the background and echo effects. TeamSpeak offers an intuitive operating system, and the ability to attach to more than one server at a time or to exchange files between people connected with the same channel.
